2 EMC Invista Network-based Storage Virtualization (SAN)

3 The Network is the Right Place for Virtualization Appliance and Controller Virtualization In-band Network Virtualization Split-path CPC DPC DPC DPC DPC State/cache introduces data-integrity risk Increased I/O latency Limited fabric ports Limited performance No state/no cache ensures data integrity I/O at wire speed Full-fabric bandwidth Scalable performance

4 Invista s Advanced Software Functionality Dynamic Volume Mobility Move and change primary volumes while application remains online Network-based Volume Management Pool storage and manage volumes at the network level Heterogeneous Point-in- Time Copies Create local copies of data for testing and repurposing across multiple types of storage

5 Dynamic Volume Mobility Invista Software Provide nondisruptive movement of volumes across heterogeneous storage Reduce planned application downtime Reduce migration costs Perform lease rollovers or technology refreshes faster Reduce lease-overlap time Increase ability to meet service levels Match storage-capacity allocation to application-performance requirements Integral component of an information lifecycle management strategy Data Path Controller Virtual volume Data Applications SAN Invista Control Path Cluster Active volume Physical storage Data Path Controller Data

6 Network-based Volume Management Invista Software Applications Simplify volume presentation and management Create, delete, and change storage volumes Provides front-end LUN Masking and mapping of storage volume to hosts Centralize management and control Single Invista console to manage virtual volumes, clones, and mobility jobs Reduce management complexity of a heterogeneous storage Single management interface to allocate and reallocate storage resources Virtual volumes Physical storage

7 Heterogeneous Point-in-Time Copies Invista Software Applications Create point-in-time copies Source and clone can be on different, heterogeneous storage arrays Enable replication across heterogeneous storage Leverage existing storage investments Reduce replication-storage capacity and management costs Maximize replication benefits to support service levels Backup and recovery Testing, development, and training Parallel processing, reporting, and queries Data Path Controller Virtual volume Clone SAN Invista Control Path Cluster Active volume Clone Clone Data Path Controller Data Physical storage

11 Rainfinity Global File Virtualization Networked Storage Virtualization for NAS and File Servers Global Namespace IP network NAS storage pool Makes NAS environments simple to manage Makes it easier to move information and resources without disruption Rainfinity Global File Virtualization File servers EMC NetApp NAS devices/platforms

12 Rainfinity Global File Virtualization Rainfinity is Out-of-Band Collecting Statistical Data on Capacity, Performance, Storage Tiers File Source Destination

13 Rainfinity Global File Virtualization Rainfinity is In-Band Transaction is submitted and enters the File Source Destination Executing Phase Rainfinity begins to copy data from source to Destination

14 Rainfinity Global File Virtualization Rainfinity is In-Band NFS Requests from the client to the Source are Re-Directed to the Destination File After execution Rainfinity goes into the Re-Directing Phase Source Destination

15 Rainfinity Global File Virtualization Rainfinity is In-Band CIFS Requests from the client to the Source are 2-Way Sync d to the Destination File After execution Rainfinity goes into the 2-Way Syncing Phase Source Destination

16 Rainfinity Global File Virtualization Usage Examples Nondisruptive Movement of Production Data Across NAS File server consolidations Lease rollover Technology refreshes Data center relocations/additions Data placement in support of information lifecycle management strategies Service-level performance optimization Synchronous replication File system archiving Global Namespace rollouts All without downtime 16
